• CGI (Compacted Graphite Iron)

- Purpose : Engine power up & reduce CO2 level by Increasing max combustion pressure (190bar)

- Benefit : Reduced weight (10%) and engine length

Bed Plate

-Improved NVH & durability

-When replacing cylinder block, the bed plate should

be replaced together (Bearing cap integrated)Upper Oil Pan - Aluminum : Improved NVH

Lower Oil Pan - Steel plate

Cylinder Block

- Aluminum cylinder head

- V6, 4 valves DOHC

- Applied plastic head cover : weight is reduced

- Integrated cam cap (ladder type) : improved NVH

- Left and Right cylinder head gasket are different

Timing System

- Duplex bush timing chain is used for S-engine.

- Exhaust camshaft is operated by scissors gears.

- Hydraulic auto-tensioner is used for timing chain.

- Oil jet is used for timing chain lubrication.

- Mechanical type tensioner is used for oil pump chain.

1 Install the camshaft locking tools (09231-3A000).

2 Align the crankshaft timing position.

3 Install the upper & lower chain guides. [Camshaft locking tool (09231-3A000)]* This tool has two components with different size

One for LH sprocket (smaller), the other for RH sprocket (bigger).

[Caution] The yellow color on the timing chain are for new part

However the color can be erased with mileage Therefore ‘O’

mark can be used instead

2 Install the tensioner lever.

3 Install the hydraulic auto-tensioner.

4 Remove the sprocket locking tools.
